Man, Thanks for that detailed how to!
I can't for the life of me get the top guide pin to tighten; both (top or bottom one) go into the support bracket and tighten up without issues, However when once I put the caliper back on and put the guide pin through and pin boot, it will not tighten up inside the support bracket........ again If I take the caliper off altogether and just insert the guide pin into the support bracket it tightens up without a hitch.
-+
Apparently whomever had the jeep before me 4 yrs ago mustve tried to replace the brake hose, or did so and rounded the bolt off so I cannot get it to loosen, so for now, the old one has to stay on.
Vise grip pliers...You mean the banjo bolt?? If uts the fitting the pliers will work gotta clamp them down hard and crack it loose. You might end up replacing the line.
Brakes can seem like a pita and for sure they are a big deal. Get it done.
I'll figure out how the heck I am going to get that one fixed asap but for now, I am left with it on. I don't even know that it needs replaced, but I will replace it as well.
sigh.
sigh.
I need a beer.

Sorry, not the banjo bolt but the one that's attached to the brake hose at the body of the Jeep. (Underneath the wheel well, which also had a torx bolt that I had to remove)
As for the issue with the guide pins, it's not stripped because I can insert then and tighten them up without going through the caliper. I guess it's just a matter of lining them up as you say, i screwed with trying to over and over for an hour and said F it. I'll be back at it in the morning
Thank you again gentleman for all your advice and help.

Ya that would be the metal brake line. Old lines are tough to get off without breaking the line. Soak it in PB blaster, heat it up, hold it stationary and apply the twisting force to the hose end, not the line, and it might not twist and break. If it does you simply replace the line as well. But you really need 2 pair of vice grips.

It would appear the issue with the top caliper guide pin not tightening up when trying to into the brake support bracket is due to the slide being a hair too long. I've take the caliper off several times and the guide pin tightens up like it should into the brake support if i don't put it through the caliper. The guide pins have so much thread on them youd think they would make them shorter so you can really get them tightened up; especially with a quick Google search that shows how many people have this issue

It's like the metal sleeve (That's in the rubber boot of the caliper mounting sleeve) is too long so the bolt won't grab.
the bolt as well as the caliper are pressed against the brake support bracket the caliper tightens up into, as much as possible.
I'm very frustrated.

Hm. You are squeezing in the rubber boot and the slide pins first as you press the caliper in, right? You have to push them (compress) them back in order to get caliper in the right position.
That said if thats not it still sounds like part of the threads in the spindle may be gone?

Well I'm upset seeing as I'm not someone who makes a lot of money and i barely get by in life. I do not have a cellphone but a cheap kindle given to me as a gift, which is my form of searching the net, so fixing the Jeep takes a lot of planning. Nothing seems to be going right. Every time I think I've got it fixed, another issue arises months or weeks later.
I was wrong when I said the brake support bracket, or whatever it's actually called, wasn't stripped. It's stripped. So the caliper cannot be securely tightened to the vehicle. I have no clue what to do or how to fix this.
Is there a way to use some sort of high temp glue that I can insert into the bracket that will hold the caliper on, I know this sounds absurd, unsafe and ridiculous but I do not know what to do.
I don't even know what size the caliper slide pin/bolt is, would getting one size larger I don't think would work because then it wouldn't fit into the metal sleeve which is inside the rubber boot that it has to go through to mount it to the vehicle.
Please please any ideas, solutions or suggestions would be appreciated.

"From what you describe you are having trouble lining it up. A flashlight with a good stand up base is key. HOWEVER, many of the spindles get the threads stripped out of them by overzealous tightening of the caliper bolt. If that is the case, you most likely will have to do what I did, drill it out and using a threaded insert tap, tap new threads into it. Then you screw a insert into it and are left with new original size threads, the whole thing comes as a kit. $30 or so at a fastner hardware store. It must be a "threaded insert tap" kit for that bolt size....Or... you can do what I did as a temp fix, stick an oversize bolt in"
The oversized bolt worked for a long while. However after getting the aforementioned kit, it was really a breeze to put new threads in and it is fixed, right. 15 min job. $30 kit, has everything you need, drill bit, tap for the inserts, tool for the tap, tool for the inserts, inserts...and you can then use it on any of the other caliper bolts, 7 if you have calipers all way round.
Ill dig up the kit and post it tomorrow. Very common problem.

I have been through this before. You MAY be able to get a slightly larger diameter bolt. The threads on the steering knuckle (where the bolts go to) have very shallow threads. I was actually able to use the same length bolt from homedepot with slightly larger diameter and it tightened right up. On the other side, it stripped pretty badly and I had to go to an insert. Yoiu can look here to see what is involved: https://www.google.com/search?q=jeep...hrome&ie=UTF-8
It's really not that bad to do just one of them. Get the insert from amazon and reuse the same bolt.
for the bleeders. I got the pneumatic one from Harbor freight and wish I had gotten it a long time ago. It does need a lot of air so if you're worried about noise from your compressor, go with the hand pump one. Will make your life much easier than any other methods.

thank you for the information. My only issue with using a larger diameter bolt is that a larger size won't fit through the metal sleeves that are inside the rubber boots of the caliper, which it has to go through then attach to the steering knuckle (I didn't know what to call that thing, so thanks)
Oh gosh, looking at the prices, theres no way I can afford that right now, a hundred bucks plus. F!....This is where an expletive is inserted.
Do you have any idea what size of bolt you used? I don't even know what size bolt the one that I have is.
Which insert did you use??
thanks
Jessica
